YouTube is celebrating its tenth birthday this weekend. Created by three former PayPal colleagues, YouTube has become more than just a social website. It has created celebrities, humiliated public figures, reminded us of 1980’s TV intros, been used as a means of propaganda, and, inevitably, it has been a potent tool of war.

But through all this, it seems that YouTube has been used primarily to watch music videos. As part of a five-part series, we here at Guides have listed the 50 most-watched music videos over the last 10 years.
